Answer:
54kg
Step-by-step explanation:
Body weight = B
Tail weight = T
Head weight = H
Total weight = F
Use equation = B + T + H = F
We are told that T = 9kg, H = T + (1/3) x B, B = H + T
We have 3 equations and 3 unknowns, solve the system of equations to find W.
B = H + 9
H = 9 + 1/3 x (H+9)=9+H/3+3 --> 2/3 x H = 12 --> H = 18
B = 18 + 9 = 27
F = 18 + 27 + 9 = 54kg
Answer:
791.28 in^2
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The diameter is 12 so the radius is 1/2 d = 1/2(12) =6
V = 3.14 (6)^2 * 7
791.28 in^2
...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer
Answer:
8.5
Step-by-step explanation:
if were finding the sum of the ones in the bracket it would be 8.5
hope it helps
(7h)^3
=(7h) (7h) (7h)
=7×7×7×h×h×h
343h^3
I use that example all the time
